Unknown Object Recorded over Nebraska During Thunderstorm

There have been other incidents of people spotting and/or recording unexplained objects in the sky in the heart of thunderstorms.

During a thunderstorm over Nebraska a dark unknown object stays relatively motionless in the sky but then suddenly shoots up into the sky.

Could it be an advanced military technology way ahead of our time? Perhaps the various sightings of UFO’s during storms are testing of new flying crafts with alternative power supplies such as using lightning to provide energy.

This is very fascinating, just what might this be?
